JPS59212525A - Ending construction of car axle - Google Patents

Abstract

PURPOSE:To have an ending construction of car axle free from obstacle for magnetic inspection of flaws without requiring use of any screw at the shaft end by forming a circumferential groove in the neighborhood of the shaft end, and by pressing a slide member in engagement with the minor dia. part of said groove toward the inner ring using a guide fitted on the shaft end and a bolt fitted on the slide member after penetrating the guide. CONSTITUTION:A circumferential groove is formed at the end part of a shaft 1, wherein the side wall of groove nearer to the shaft end shall be in a tapered surface 1A, and the other side wall farther from the shaft end is formed in a plane perpendicular to the axis of the shaft. A slide member 4 is fitted in this circumferential groove with a clearance in the circumferential direction, and the inner edge and outer edge of one side of the member 4 have tapered surface 4A, 4B, wherein the surface 4B shall mate with the abovementioned tapered surface 1A of the shaft 1. A guide 5 fitted on the shaft end as movable in the axial direction has a tapered surface 5A to mate with the tapered surface 4A of the slide member 4 and a hole for insertion of a bolt 6. After penetrating the hole in the guide 5, this bolt 6 is fitted in a threaded hole in the slide member 4.

With the nut 3 that has been cut off, retighten it if L, and put the key 4 on the protruding part of the nut 3 with the key 4 and the bolt 5 to prevent it from loosening. But the car! 1I11 is advantageous because it protects the depth of the threaded part, requires sufficient notes for heat treatment and processing, which tends to increase costs, and also has a locking hole at the shaft end. However, the present invention aims to solve the above-mentioned deficiencies in the conventional row, that is, to eliminate the need for a screw at the end of the shaft of the base shaft. , 11B.

It was inserted for the purpose of providing Kitan-Kinkensuke with the basic structure of the Shoshaku.

In order to accomplish the above-mentioned object, the present invention also provides a method for moving the inner ring to the axle by pressing the inner ring to the right side of the opposite end of the axle. The shaft end structure of the base shaft that shoulders the inner ring pressing member to be fixed to the axle is formed in a 1jiJ vehicle drawer, and the shaft end 1HIJ is arranged on a stepped portion with a large diameter portion and on a small diameter portion of the axle, and is arranged on the stepped portion. Pressed side wall and bolt hole gauge: Il + end pressing part Ishi,! ! The III press member is screwed into the threaded hole, and a force r in the direction of the IllIII end is applied to the +I+III press member to press its side wall against the stepped portion. The inner ring pressing part 1 is bent by the reaction force of the stepped part due to the pressure of the locking means and the connecting means.
A fixing means for fixing the inner ring to the axle by pressing 1-1 in the direction of force 1lJ+'a is included.

In the above, embodiments of the present invention will be described based on corner surfaces.
